Greg Zimmer - Senior Product Marketing Engineer Nov 4th 2015
Electromagnetic Radiation (EMR), Electromagnetic Interference (EMI) and Electromagnetic Compliance (EMC) are terms that pertain to energy from electrically charged particles and the associated magnetic fields that can potentially interfere with circuit performance and signal transmissions. With the proliferation of wireless ...

High Voltage Inverting Charge Pump Produces Low Noise Positive and Negative Supplies

Martin Merchant - Sr. Applications Engineer Oct 1st 2012
Introduction Dual-polarity supplies are commonly needed to operate electronics such as op amps, drivers, or sensors, but there is rarely a dual-polarity supply available at the point of load. The LTC®3260 is an inverting charge pump (inductorless) DC/DC converter with dual low noise LDO regulators that can produce positive ...
